"his invention relates to narrow fabric looms of the type commonly used in weaving` ribbon, tape, and the like and having a plurality of shuttles reciprocated in uni'- the invention yis concerned with an improved formY of drive mechanism for reciprocating the shuttles and a novel shuttle construction with guide blocks therefor, these features improving' the loom so that it may be run at a higher rate of speed and more quiet# ly than looms as now constructed. In addition, by the use of these novel features, the mechanisml is simplified, has greater durability, and is capble of easy adjustment when occasion arises, so that a loom constructed to embody the features of my invention produces fabric at a greater output rate and operates for longer periods without shut-downs on account of adjustment or replacement of parts. v

In narrow fabric looms as now in common use, the shuttles are made of box wood and are mounted in one or more rows 1n wooden guides on a batten, each shuttle being `guided between pairs of blocks, with one pair at each side of which the warp threads form of drive mechanism the shuttles includes a rack bar on the batten for each row of shuttles, the teeth of this bar meshing with pairs of pinions which are disposed between thc guide blocks, one at each side of each reed. These pinions into the shuttle race-ways and mesh with rack teeth formed in the rear faces of the shuttles, so that as the rack bar is reciprocated, it rotates the pinions which in turn canse movement of the shuttle back and forth through the shed. The mechanism for reciprocating the rack bar includes the main drive shaft which drives another shaft through an elliptic and an eccentric gear and this second shaft is provided with crank arms to which are connected leather straps. These straps are connectedl to the rack bar at spaced points near one end of the bar and in the operation of the device the straps are alternately taken up and let out by the motion of the crank arms to preduce a recipropass. A common for reciprocating` the reed through eating motion o f the group of shuttles with a period of rest at each end of the path of travel,fso that suiiicient time is allowed for the shed to form. e

VThis type of shuttle drive is open to numerous objections, as for instance, frequent adjustment is required because of variation in the lengths of the straps, due to weather conditions and normal tendency to stretch. Also, as the shuttles, rack bar, pinions, an guide llocks have heretofore been commonly made ofA wood, as climatic conditions change, the wood frequently changes in size Y to an extent such that the parts get out of adjustment and bind or work loose. This causes a breakage in the teeth of the racks or pinions and necessitates replacement which is an item of considerable expense, since the loom must remain idle until repairs can be made. Sometimes the teeth of the bars and pinions become worn and break, which again results in a 'complete shut-down of the loom and may also involve a considerable loss in ends. Again, the variation in the lengths of the straps and the wear on the teeth of the racks and pi'nions makes it impossible to maintain the shuttles under exact and positive control at all times in their movements, and as the shuttles attain a eonsider. able momentum in movement, looseness in the driving,r parts permits the shuttles to overrun and rebounft. Also, for the same reasonthe rest period in the movement of the shuttles which occurs at the endy of each reciprooation is not of exact duration and as aconsequence the operating part-s of the loom may become damaged andy frequently damage to the warp occurs.

The present invention is directed to the provision of a 'shuttle drive for narrow fabric looms` employing` a multiplicity of shuttles which overcomes the diiiiculties above pointed out and affords important advantages,

due to its longer life, resulting from the elimination of working parts and more satconstructed, and a loom which embodies the features ot' my invention represents a saving in instailation and maintenance costs and a lower operating expense, due to t-hc higher output rate.

rlhe shuttle drive of the present invention may be embodied in different forms ot' mechanism, but preferably includes a pair of elements for driving each shuttle which may take numerous .iforms but may most conveniently be made as plates of semi-circular or quadrant shape mounted at intervals on a rod which extends lengthwise oi" the row of shuttles. Each shuttle is provided with a slot at each end and the rod with its plates is mounted in a sliding frame which has a reciprocatory movement corresponding to that to be given the shuttles. in the reciprocation of the rod, asthe hatten moves back and forth, the rod is rocked so as to move one or the other of the pair of plates into one of the slots in the corresponding shuttle and the shuttle is moved by this plate for a part of its passage through the shed. At the start of each shuttle movement the plate which is in effective position engages the slot at the trailing end of the shuttle, while the other plate which is placed in a different angular of the threads of the shed. The plate so engaged with the shuttle establishes a driving connection between the shuttle and the rod and causes the shuttle to be moved as the rod is moved. When the leading edge of the shuttle has passed through the shed so that the channel in the shuttle is exposed, the rod is rocked so as to cause the previously operative plate to release the shuttie, while the previously inoperative plate enters the channel. lhe shuttle movement is now completed, with the second oi" the plates active and this plate remains in operative position until a part of the return movement of the shuttle is completed, when the rod is rocked to its original position.

The endwise movement of the sliding frame in which the rods, one for each row of shutties, are mounted ina-v be produced by various devices but i prefer to employ a novel type ot cam mechanism which includes a plate with a pair ot cam grooves in which enter rollers carried by a slide bar. This sliding bar is given a reciprocatory movement by a suitable eccentric and in the course of this movement the bar is moved bodily sidewisc by engagen'ient of the rollers in the cam slots. A driving connection between the bar and the sliding frame is provided by means ot a pair ot pins or rods mounted on the frame and lying on either side ot the bar, and the arrangement is such that as the frame carried by the hatten moves back and forth, a continuous driving connection between the frame and the slide har is maintained. it suitable intervals in the movement ot the iframe it is position on the rod, lies at one side reciprocated by the bar to cause a movement of the plate-carrying rods and the shuttles driven thereby.

Another novel feat-ure of the invention involves the provision of a shuttle construction which is not subject to difficulties arising from variations in humidity conditions. The improved shuttle includes a wooden body portion with a fibre plate on its rear face. This plate slides in guideways formed by a pair of slotted metal plates of light construction.` rlhe fibre sliding in smooth channels in the metal plates is of indefinite life and since such libre is not subject to warping and shrinking as moisture content of the air varies, binding or seizing oi 'the shuttles in the guide blocks is prevented.

For a better understanding of the invention, reference may be had to the accompanying drawings,in which l? ig. 1 is a fragmentary view in front elevation showing a hatten on which one form of the new shuttle drive mechanism is mounted,

F ig. 11 shows a portion oit a modified form of' drive mechanism, somewhat similar to that illustrated in Fig. 4.

Referring now to the drawings, the loom which is in the main of standard construction, includes a batten 10 of the usual or any standard construction, which includes an upper rail 11 and a beam 12 connected by the usual straps 13 at suitable intervals. As illustrated, this hatten is provided with two rows of shuttle raceways defined by upper and lower guide blocks 14 and 15 respectively mounted on the straps in any convenient manner 'and preferably by an adjustable mounting which permits the upper and lower blocks to be adjusted toward and away from each other so as to increase or decrease the width ott the shuttle raceway between them. The guide blocks are channeled as illustrated at 16 in Fig. 2 to provide a slot for the iibre plate 17 with which each of the wood shuttles 18 are provided. Aside from the libre base'plates, the shuttles may be et standard construction.

The blocks 14 and 15 are of light metal construction, such as iron castings, and are made single and double, as illustrated. y The double iso block 14 includes a pair of individual blocks 19 which form part of the raceway for a single shuttle and are disposed at either side of a reed which occupies a space designated 20. The portions 19 are connected by an extension piece 21 which passes across the space occupied iy the reed but is offset to a suiiicient extent beyond the-portions 19 as to provide suitable clearance for the warp threads passing through the reed. Associated with each double block 111 are the single blocks 15 mounted on the straps 13 one on each side of the space 2O tor a reed. Vith this arrangementthe slots 16 in the faces of the portions 19 et' the double block may be accurately formed and in a plane and the single blocks 15, by reason of their adjustable mountings, may then be properly aligned with the portions 19 so that a raceway is formed between the blocks in which the shuttle may move without binding. This combination of metal shuttle guide blocks and shuttles vwith ibref plate members which move in the raceways formed by their blocks eliminates di'liiculties heretofore of great importance arising from warping or shrinking of the wood blocks and shuttles previously used, and at the same time the weight of the reciprocating shuttles is not added to, since the shuttles with the light tibre plates are not substantially difieren-t in weight from the all-wood shuttles now in use.

Each shuttle is provided with a pair ofY channels or grooves 22, one at each end of the shuttle, these channels being formed either in the upper or lower face of the shuttle, depending on whether the shuttle is to be placed in the upper or lower row in the batten.

he shuttles are symmetrical in form so that they may be used in either row simply by turning one face or the other uppermost. In order to reciprocate the shuttles, I may employ different forms ot' my invention both operating on the same principle. In one of these forms the hatten is provided with brackets 23 secured to the straps 13 and extending iiorwardly over the uppermost row of shuttles. r'lhese brackets are provided with blocks 24 which are undercut so as to receive a slide bar 25 having depending brackets 2G terminating in bosses 27 in which is mounted a rod 23. At suitable intervals this rod is provided with collars 29, one ou each side oi' a boss 27, so that the rod, while iroe to rock in the boss, is incapable of endwise movement with reference to the boss. fit one end of the batteri beam 12 the rod 23 passes through a bracket 30 on a plate 31, this plate having a depending bracket 32 on which is mounted a shaft 33 carrying a bevel gear 34 meshing with a smaller bevel gear 35 on the end ol' the rod 28. At its rear end the shaft 33 carries a forked arm 36 tast thereon and on a stud 37 in the bracket 23 is mounted a roller 33 in a position to be received between the spaced ends ot the arm 36.

between a pair of The arrangement ot the parts above described is such that as th slide 25 is moved in one direction in the hatten, the forked arm 36 straddling the roll 38 on stud 37 is rocked through o and through the shaft 33 and gears causes the rod 28 to rock through 1300. At spaced intervals on the rod 23 are plates 39 of quadrant form arranged in pairs and spaced apart a distance equal to the distance grooves in the opposite ends ot the shuttle. These quadrants are angularly offset 90 on the rod 23 and the ar rangement is such that at the startoit movement to the right, asillustrated in Fig. 1, the quadrant 39 at the trailing end ot each shuttle is in operative position, that is, the

rod 28 has an angular position in which thisA quadrant enters the channel at the rear end of a shuttle 18. Upon mov-ement of the slide 25 toward the right, the rod 23 is carried along with it, and t-he quadrants which are in operative position establish driving connections between the shuttles in the row and the rod 28, while the quadrants 39h, which are not in engagement with shuttles, occupy a Aposition in which they will not interfere with the shed as the rod moves. lWhen the slide 25 and the shuttles driven by it have moved to an extent such that the leading end of each shuttle has passed throughthe shed and the channel in this end o'rf each shuttle is exposed, the rod 28 is vrocked by engagement oit the forked arm 36 with the roller 38 mounted on' the stationary stud 37 on the batten frame, and upon such rocking the quadrants 39b`move down to enter the channels in the leading edge of the shuttles, while the quadrants 39a are raised out et their respective channels and take a position so that they will clear the sheds passing through the reeds in the spaces 20. The rod 2S occupies the new angular position until the completion of the shuttle movement, and until the return movement has progressed to an extent such that the leading end oft each shuttle has again passed through its shed, whereupon the rod'is rocked to itsoriginal position and quadrants 39 complete the shuttle movement, while quadrants 39 are raised to the inoperative position illustrated in Fig. V1.

The shuttles ot the upper row are operated by quadrants placed on a rod which lies above the row of shuttles, while the shuttles of the lower row are operated by similar mechanism, but the rod and quadrants for these shuttles are placed beneath them. Other minor changes in construction are necessary in this arrangement. The rock rod 28a of the lower group is mounted in brackets 26a secured to a slide 25:L which is secured at one end to a member 31 disposed at one end ofy the batten. This member 31n has a pair of spaced channels 43 in its lower tace in which are received the upstanding legs la y and plates for each row of of a U-shaped bracket l5 secured to the batten beam. rlhe member 3lt is provided with a bracket 30 through which the rod 28a passes, and the rod is rocked by gears and a forked arm and pin similar to those previously described in connection with the upper mechanism. 'llhe two members 3l and 3l2l are connected by a cross bar and between these members are mounted rods ll carrying cylindrical sleeves 48. Betw an these sleeves passes a slide har i9 which is given a reciprocatorv movement equal to the throw of a single shuttle and as the be /m reciprocated, all of the shuttles are moved back and forth across the sheds bv the rock rods 28 and the quadrants. ln Fig. l, the parts are shown in the positions the;7 occupy at the start of their movement to the right, as indicated by the arrow.

The operation of the plates is more clearly illustrated in Fig. 5, in which the view a shows a single shuttle of the lower row at the beginning of its movement to the right. Here the quadrant 39a is eng ged in the channel in the shuttle at the trailing end thereof, while the quadrant 39 is in a downward position. llVhen the shuttle i8 is in the position illustrated in Fig. 5b, the leading end of the shuttle has passed through the shed and its channel is exposed. As soon as the shuttle has reached this position, the rod 28L is rocked to bring the quadrant 39D into operative position and in engagement with the channel in the shuttle, while the quadrant 39a has moved clear of its channel and down sothat it will. clear the shed without interference. Upon completion ot the roel;- ing of the rod 28, the quadrants are in the position illustrated in Fig. 5c, where the quadrant 391 is in full operatingl position and the quadrant 39a has been carried to a point where it will not interfere with the shed through which the shuttle passing.

ln the construction described,y each row of shuttles is provided with a member extending the length of the row and carrying means for establishing an operative connection between the shuttles of that row and the meinber, but instead of using separate drive rods shuttles, the rows of shuttles may be placed close together and the shuttles of both rows driven by means of a single rod, in which event the construction illustrated in Fig. 6 will be employed. This construction lf prefer on account of its simplicity, although for certain widths of fabric, the construction illustrated in Fig. Imay be used to better advantage.

ln this preferred construction there is provided a slide bar 50 mounted in any convenient manner, as, for'example, in a groove formed between adjacent shuttle guide blocks of the upper and lower groups. This slide bar is arranged for reciprocating movement and carries brackets 5l. in which the the space 57, while the plate 531 rock rod 52 is mounted. This rock rod is provided with semi-circular plates 58 spaced at suitable intervals. The shuttles of the upper row, as illustrated in Fig. 7, are provided with channels 54 at opposite ends and in their lower faces, while the shuttles of the lower row have similar channels but in their upper feces. The channel in the left-hand end of a shuttle of the upper row is opposite the channel in the right-hand end of a shuttle of the lower row and alternate plates 53 havel an angular spacing of 18()O on the rock rod. The spacing of the shuttles is such that when the bar is rocked to one position, one plate is in operative connection with the left-hand end of a shuttle of the upper row, while the next plate is in operative connection with the left-hand end of a shuttle of the lower row. At the beginning of 'the shuttle movement, the rod is rocked so that the plates establish an operative connection between the rod and the trailing ends of the shuttles in the two rows, and this relation of the parts continues until each shuttle has passed through the shed and its forward end is exposed.. Thereupon the rock rod is moved to a position in which each plate releases the shuttle with which it was first engaged and engagesl a shuttle of the opposite row. rlhe movement of the roel: rod and the position of the plates on it is such that when a plate is engaged with shuttle of one row, it will clear the shed through which its associatedshuttle of the other row passes, and at the beginning of each shuttle movement each shuttle is moved by a plate which engages its trailing end and the shuttle movement is completed by a plate which engages its leading end.

ln Fig. 7 the plate 53L is in engagement with the trailing end of the shuttle 18 and in a posit-ion in which it will clear the shed in is in engagement with the trailing end of the shuttle 18b and in a position in which it will clear the shed in the space 60. When the shuttles have moved to the position illustrated in Fig.

8, the plate 53ZL is moved by rocking of the rod 52 to a position in which it engages the leading end of the shuttle 18C, and is completely free of the shuttle 18a. The plate 53h has been moved down to engage the leading end of the shuttle 18a and has thus freed the shuttle 18h. The shuttle 56 is now moved to the end of its path of travel by the plate 53h and the plate 53FL passes over the shed in the space 60. On the return movement the cycle of opera-tions is reversed.

The mechanism for moving the slides 25 and 25a back and forth includes the bar i9 which passes between upright bars l? eX- tending between the members 3l and 31a secured to the ends of the slides. The bar 49 is provided with cam rollers 63 at its opposite ends which run in slots 64 in spaced plates 65 and 66 secured to the end members of the y The( plate 65 has an extension 67 on which a leyertlS is pivotally mounted'on a stud69. rlhe :tree end of this lever is connected by a link 7 O` to the end of the rod 49 and between its ends the lever is connected to a link 71,

the other end ofv which is mounted on an ec'- centric pin 72 on a gear 73, meshing with a gear 74 on the vertical shaft 75. These looms are normally provided with a jacquard pattern mechanism driven by a vertical shaft, and this shaft may be that designated in the drawings. Vith this arrangement of the parts, upon rotation of the gear 7 3 the lever G8 is rocked y is transmitted through the link 70 to the bar 49. The bar reciprocates back and forth in the same direction as the batten swings and in the middle of its reciprocating movement the bar 49 is moved bodily sidewise by reason of the engagement of the rollers 63 in the cam slots 64. In this bodily sidewise movement the bar 49 causes a movement of the slides 25 and 25a connected together and provided with the rods 47 extending between them. Preferably these rods are mounted in bracket bearings 7 6 which are secured to themembers 31 and 3lil by a slot and pin connection, as illustrated at 77 in Fig. 4, and this permits the rods 47 to be adjusted in position with reference to the bar 49 so that the desired clearance may be secured and` the position of the rods may be adjusted with `reference to one 'another as wear occurs.

lV ith this arrangement, a positive' driving connection is insur d between the bar 49 and the slides by which the shuttles are driven, and the shape of the cam slots determines the extent of the throw of the shuttles.

lt will be noticed that the cam slots are provided with a dwell at each'end representing` a'period of restin the shuttle movement at each end of the'path of travel of the shuttle and in between these dwells the slots areV disposed at an angle to produce a shuttle movement at the desired speed. vIf the shuttle throw is to be varied, then plates with different types of slots will be substituted for those designated 65 and 66, and some changes in the linkage may also be necessary.

In some installations it may be desirable to have the operating mechanism for the slide bars mounted on the floor or in some other position, instead of at theend of the loom frame, and in such a situation the modified driving` mechanism illustrated in Fig. 1l will be employed.y l-lere the plates 65 and 66 are mounted on the floor and the rod 49 is connected by means of a clamp 7 8 to a pivoted lever 79 extending through a clamp 80 pivotabout its pin 69 and its movement 'Also, the durability of the parts vment of the parts is simple.

ally mounted on a rod 8l which is supported in an upright member 82. rlhe free end of the lever 79 is slotted, as indicated at 83,' and a pin 84 on a cross member extending between the slides 25 and 25 lies in the slot 83. rlhe slotted end of the lever is connected to the remainder by a joint`85 and the clamp 8O permits endwise movement Yof the lever 79 through it. The rod Sl is adjustably mounted inthe upright 82 so that the clamp 80 which servesas the pivot point of the lever, may be placed at different positions. vWith this arrangement, as the rod 49 is moved sidewise bodily it swings the rod 79 about the pivot point of the clamp 8O as a center and the free end of the rod causes the reciprocating movement of the slides. rlhe joint 85 permits the connection to be maintained between the lever 79 and the slides during the swinging movement of the batten.

vIt will be seen that in the new loom the shuttles in one or more rows are reciprocated as a group by a single element carrying means yby which an operative connection between the element and the shuttles is established. These means are arranged to operate to establish a connection between thetrailing end of each shuttle and the reciprocating member at the start. of each shuttle movement in each direction, and then as soon as each shuttle has passed partlythrough its shed, the original connection is broken and a new connection is established between the member and the leading end of each shuttle. The quadrants or semi-circular plates used for establishing the' connection are so disposed on the rock rod ,that in the rocking of the latter at one instant in the shuttle travel, the shuttle is engagedboth at its leading and trailing ends, but immediately thereafter one or the other of the elements on the rock rod is released from the shuttle. The consequence is that throughout its movement and while it is at rest, the shuttle is always operatively connected with the rock rod, but not by the same element on that rod. Accordingly, each shuttle is under positive control at all times and overrunning, with theV consequent rebound and variation in the rest period of each shuttle, is avoided. 'The quadrant or semi-circular plates on the rock rod are preferably made of' light metal and as the shuttle guide blecks are likewise of metal and the parts of the shuttle which lie in these raceways are of fibre, difliculties such as occur with wooden driving and guiding devices are overcome. is greatly increased and as the parts move freely and are under perfect control, a much higher loom speed fis obtainable.. blocks are constructed in such a way that perfect alignment is readily secured and adjust- The original setting up of the mechanism is extremely simple because all that isnecessary is to place all The new guide f the shuttles at one end of their' path of travel, set the slides in the proper relation, and then adjust the plates on the rods in the proper positions. Each plate has a boss through which the rod extends and the plate may be secured to the rod in proper angular position by means of a set screw. Once the plates are properly placed, no change is vnecessary in their setting, and as all the parts are in exposed position where they are readily accessible, adjustment or replacement does not necessitate shutting down the loom for any considerable length of time.

rIhe new cam mechanism for driving the slides is of simple construction and positive in action and it avoids the use of leather straps and of elliptic and eccentric gears such as have Aheretofore been necessary and are a constant source of annoyance and diliiculty.
